Automation Business Unit American Global Products Science & Technology Quality • Excellence • Support The Internet 0 Value Proposition € n IP at all Levels o Current models require different protocols and translation to communicate o The SE model uses IP communications at all levels; no translation. n Cost Effective for Simple The Competitor’s Model Devices By using the power lines for communication, Internet 0 has a lower port cost and installation cost. o The potential total cost for components can be < 1 € o There are no cabling costs o The Schneider Electric Model Automation BU/Connectivity and PS/AGP – T. Snide – 10/12/2006 <€ 2

Automation Business Unit American Global Products Science & Technology Quality • Excellence • Support Potential I 0 Applications for Schneider Electric Push Buttons Pilot Lights n Industrial Automation o The first target devices are simple items such as push buttons, pilot lights, relays, thermometers, etc. o Devices that do not change state often and can support a low data rate (1 megabit per second). o The first Schneider Electric version of Internet 0 Devices are 24 Volt DC based. n Building Automation o Lighting, HVAC applications, sensory, energy savings n Electrical Distribution o MCC panel network n As the Internet 0 network is proven Relays Automation BU/Connectivity and PS/AGP – T. Snide – 10/12/2006 reliable, higher-end devices can be supported. 3

Automation Business Unit Quality • Excellence • Support American Global Products Science & Technology Why this demonstration? n To address three key questions about the technology o Will it work in Schneider product applications? o What are the technical capabilities and limitations? o Are the per node costs as advertised? Safety HMI Controller Motor starter Motion Drive I/O Power supply I/O n We chose the Schneider Electric All in one panel Automation BU/Connectivity and PS/AGP – T. Snide – 10/12/2006 architecture to help validate the Internet 0 technology o It is a fully contained network usually with a communication path to a control network which closely matches our prototyping model. o It has sufficient number of devices using 24 volts DC where most of the communication will be local to the panel. o Each panel has a different function which will prove out our networking model for Internet 0 4

Automation Business Unit American Global Products Science & Technology Quality • Excellence • Support Project Status n A network of 25 Internet 0 nodes has been developed using simple Industrial Automation devices. o Pilot-lights, push-buttons and push-button/pilot lights. n A simple Internet 0 SLIP bridge is used to interface to a computer. n The network operates at 24 volts DC. n The networks at its original speed with no speed improvements added at this time. (about 400 kilobits per second) n The maximum distance for communication between 2 nodes to date has been 31 meters. o The signal was degraded but the true distance limit of communication has not been determined but is certainly longer than 30 meters. n The only connection to the node and device combination is the two wire power lines.

Automation Business Unit American Global Products Science & Technology Quality • Excellence • Support Opportunities: n Performance characterizations o More randomized traffic from several nodes o Perform 4 -corner testing; max # of nodes, max. distance, max daisy-chain o Include some “noisy” devices in the network n Performance improvements (without added cost) o Currently the bit width, time between bytes and time between packets is fixed and very long, shorten the time between the bytes and packets o Enhance the collision detection o Allow packets to be interleaved during transmission o Optimize the current code o Increase the internal operating speed of the processor n Performance improvements (increased cost) o Run the processor at 20 MHz using and external crystal and capacitors n A trade-off between network speed and node cost will need to be characterized Automation BU/Connectivity and PS/AGP – T.
